FrameAxis — Camera Composition Guides for Marmoset Toolbag 5

Frame your shots faster and with more confidence.

FrameAxis adds a lightweight camera-composition overlay to Marmoset Toolbag 5, giving you accurate visual guides while you position cameras and refine presentation renders.

The guides live entirely in screen space: they do not create scene objects, do not modify the active camera, and never appear in exported images or videos.

INCLUDED GUIDES

• Frame boundary

• Center lines

• Rule-of-thirds grid

• Golden-ratio grid

• Diagonals

BUILT FOR PRACTICAL CAMERA WORK

• Enter an exact render width and height

• Get and fit the current Render resolution with one click

• Fit the overlay to the exact aspect ratio inside Toolbag's active viewport

• Use Frame Size % to scale the guide area without edge dragging

• Reposition or resize the overlay manually whenever needed

• Customize guide color, opacity, and line thickness

• Click-through locked mode keeps the viewport fully usable

• Preferences are saved between sessions

Use it for portfolio renders, product shots, character presentations, turntable cameras, thumbnails, and any scene where composition matters.

COMPATIBILITY

• Marmoset Toolbag 5

• Windows 10 or Windows 11

• Tested with Marmoset Toolbag 5.02b

• No third-party Python packages required

This release is Windows-only because it uses a lightweight native Windows overlay.

FAQ

Will the guides appear in my render?

No. The overlay is screen-space only and is never part of the scene or final render.

Does it modify my camera or scene?

No. It creates no scene objects and does not change camera settings.

Can I type an exact camera or render resolution?

Yes. Enter width and height, then click Apply Resolution. You can also click Get + Fit Render Res to read Toolbag's current render resolution and fit it inside the active viewport automatically. Manual drag and resize remain available.

Can I change the grid appearance?

Yes. Color, opacity, line thickness, frame size, and individual guide types are adjustable.

Does it work on macOS or Linux?

No. Version 0.3.0 is Windows-only.

Does it require extra Python packages?

No. Everything required is included with Toolbag and Windows.
